To a]! whom (1L may concern:

Be it known that l, PATRIK L. PETERSON, tizen of the United States, anda resident of North Grosvenor Dale, county of Windham, State ofConnecticut, have invented an Improvement in Back-Stops for Pie-ker-Sticks, of which the following description, in connection with theaccompanying drawings, is a specification, like numerals on the drawlugs representing iike parts.

This invention has for its object the prod uetion of a novel hack-stopor positionim device to eoi'iperat-e with a loom picker-stir on itsoutward stroke and stop the same at the desired point.

The back-stop is adjusiably mounted on the la to take up wear whennecessary and also to regulate the stoppinp and starting, point of thepicker-st iek.

The various novel features of my invention will be fully described inthe subjoined specification and particularly point-ed out in thefollowing: claims.

Figurel is a h'ontelevation, )a'rtly broken out,of one end of a loom-layand the adjacent picker-stick with one embodiment of my invention inoperative. position. Fig. :2 is a rear elevation of the lay, showing themeans by which the back-sto is ad just-ably secured in position; andFig. 3 1s a perspective view ol the back-stop detached.

The lay longitudinally slotted at .2 in usual manner for the swingingpicker-stink 3, the binder 4, cover-plate 5, and front boxplate 6, Figs.1 and 2, may he and are all of usual or well-known construction, thepart 7 of the lay forming the outer end of the slot 2, being cut away,as at 7*, Fig. l

Various devices have been provided to stop the picker-stick at. theouter end of the lay, such devices being more or less ellieieut andemivenient and depending, on springs, springeontrolled stops orpneumaticv devices lo] their operation.

In my present invention l have provided a hack-stop which has greatsimplicity and strength ol construct-ion and which is secured in anadjustable manner on lhe la so llnu the stopping-point. ol' thepiclu-r-sliek can be regulated as desired and wen r taken up, the use ofsprings ors wing-eonlrollerldevieesai-nl pneumatic stops or cushionsbeing wholly obviated.

Referring to Fig. 3, a flat elongated stand 8 is dropped at its outerend at. 9 and continued as a lateral arm ll) at right angles tothestand, the outer end. of the arm being onlar 'ed to form a heavy andrigid hack-stop l1 having a convex face 12, recessed at top and bottomat 13. A piece of leather, rubher, raw-hide, or other suitable material,as 14, is s u'ung into the recesses over the face 1:2 oi the back-stopto provide the impact face or surface against which the picker-stickstrikes atthe. desired point. of stoppage on its outward stroke. 1 forma guideway on the rear side of the lay by means of two parallellongitudinal ribs 15 (see Fig. 2) adjacent the end of the lay, theguidewa being wide enough to permitthe. stand 8 to he slidably seatedtherein, the arm 10 extending across the lay below the end portion 7 ofno slot 2, the drop 9 permit-ting the arm to do so. The arm 10 is ol"such length that. the hack-stop is laterally oll'setfrom the stand inthe path of the picker-stiek on its outward stroke, as will he manifest,the convex portion of the hack-- stop or,ra-ther, the impact. member 14taking, the blow of the picker-st.iek. A slot 16 in the stand receives abolt 17, Fig. :2, extended through the rear portion ol" the lay, a nut-18 on the bolt elamping the stand firmly in position on the law. Byloosening the nut. the hack-stop can beudjusted inward or out-ward asnecessary, the guideway sustaining the stand and preventing anydisplacement thereof or olthe back-stop. and alter the nut 18 is setupthe device is rigidly secured in the desired )osition on the lay. Thestand, arm, and lniek-stop are conveniently made as an integral piece byens-tin; or forging, and when the impact member l4 becomes too much wornitean be removed and a new one readily inserted, the position of therecesses l3 holding it. in place wil hout other fastening.

The device is cheap, strong, and durable,

it is adjusled and elamped in place by a. sin-' gle clamping member, andforms an ell'eetive stop for l he pirker-sl Eek.

Having fully described my invention. what I elaim as new, and desire tosecure by Let.- ters I'll-tent, is-

1. A lay longitudinally slot-led l'o'r the l and to stop the outwardstroke of the piekerpicker-stick, mrallel longitudinal guide-ribs on therear Si! 0 of the la near its outer end, a hack-stop having eon vex,face in the path of and to stop the picker-stick on its outward stroke,a non metallic inning dotar-hahiv secured to the hack-stop and lyingagainst. the eonvex face thereof, a stand rigidly eonnecterl with andlaterally offset from the hack-stop and slidahl mounted between theguide-ribs, and adjustable means to clamp the stand to the la}- andthereby position the hack-stop.

.2. A lay lmwitudinally slotted for the picker-stick and having alongitudinal guideway near the out-er end, a slotted stand slidnblyseated in the guidewzav, a clamping-lwlt o secure it in adjustedposition, a r1gi(.ll \-'-attached metallic hack-stop laterally oll'set.from said stand and positioned in the path of stick, and a renewableleather facing to co er the fareof the back-stop.

3. 'A lav longitudinally slotted for the picker-stick, a metallichack-stop in the path of the picker-stick on its outward stroke, saidhack-stop having a convex face and transverse, pa rallelretaining-recesses at the upper and lower ends thereof, a leather iniact member removahly held in place by suit recesses, covering andresting against the convex face. of the back-stop, and means toedjustal'ily attach the hack-stop to the lay.

In testimony wl'lereoi' I have signed my name to this specification inthe presence of two subscribing witnesses.
